Frequently asked questions
Is the QR code free to use commercially?
Yes. QR codes themselves are an open standard — no licence or tracking is added.
What size should I print it?
Minimum 2cm × 2cm for handheld scanning, 10cm+ for posters seen from 1m away.
Does the QR code expire?
No — it encodes the URL directly. As long as the form URL works, the code works.
